Answer:

the complex numbers have opposite real parts

The true statement about the complex numbers is,

''The complex numbers have opposite real parts.''

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

The sum of two complex numbers, where the real numbers do not equal zero, results in a sum of 34i.

Since, The sum of two complex numbers are 34i which is an imaginary number.

Hence, The complex numbers have opposite real parts.

Thus, The true statement about the complex numbers is,

''The complex numbers have opposite real parts.''

Answer:

B, Gina, $0.02

Step-by-step explanation:

Per pound is $1.38, so split it in half to get $0.69 for half a pound.

Then you have 1.38 + 1.38 + 0.68 = $3.45 total for Gina.

Per pound is $0.98, if you split that in half you get $0.49 for half a pound.

Add it up, 0.98 + 0.98 + 0.98 + 0.49 = $3.43.

You can see Gina spent more, and then you subtract 3.43 from 3.45 and get $0.02.

Answer:

1667 carpets.

Step-by-step explanation:

For this problem we have to find the

area of room,

area of 1 carpet.

Then we have to find how many such carpet's sum will be equal to area of room.

_______________________________________________

area for rectangle is given by = length * width

area of room = 10 m * 15 m = 150 m. sq.

dimension of carpet = 30 cm * 30 cm

lets converts first 30 cm in meter so that dimension of room and carpet are in same unit that is in meters

100 cm = 1 meter

30 cm = 1/100 * 30 meters = 0.3 meters

area of 1 carpet = 0.3 m * 0.3 m = 0.09 m. sq.

let there be need of x carpet to cover the floor of room.

area of x carpet = area of 1 carpet *x

area of x carpet =0.09x m. sq.

area of x carpet = area of room

0.09x m. sq. = 150 m. sq.

x = 150/0.09 = 1666.67

Thus, there will be need of 1666.67 carpets but carpets cannot be in fraction

hence rounding the number of carpet to nearest whole number.

there will be need of 1667 carpets.

Answer:Your calculator should now display a screen with these variables. I have written what each

variable stands for next to the variable. You calculator likely has numbers next to some of the

variables. This is okay. We will type over them when we need to solve a specific loan problem.

N Number of payments

I% Annual interest rate

PV Loan amount (Normally

entered as a POSITIVE

number in loan problems.)

PMT Monthly payment amount

(Usually entered as a

NEGATIVE number in loan

problems.)

FV Balance when loan is paid

off. (Usually 0 in a loan

problem.)

P/Y Number of payments per

year. (Usually 12 in a loan

problem.)

C/Y How often interest is

charged. (Usually 12 in a

loan problem)

Begin / End Choose Begin if you make a

loan payment the day you

take your loan. Otherwise

choose End. We will always

leave this on END.

Example: A new car is purchased and a $25,000 loan is taken. The loan is for 6 years (72

months) and the interest rate is 4.9% compounded monthly. What is the monthly payment?

Calculator steps: Hit APPS button then select Finance then select TVM solver.

We will solve most of the problems in this chapter from this screen. We need to know what

each variable represents. We will enter values for every variable except for the one we are

solving for. We are computing a monthly payment. We will put values in for every variable,

except (PMT). PMT stands for the payment.

Enter these values on your calculator.

N (number of payments) 72

I% (annual interest rate) 4.9

PV (Loan amount, make

this amount positive.)

25000

PMT Move cursor here and hit

green alpha button then

enter after you have entered

every other value.

FV (what you owe after

make all payments)

0

P/Y (payments per year) 12

C/Y (how often interest is

paid)

12

Begin / End

(We will always leave this

on end.)

End

Once you have entered all of the amounts scroll up to PMT. Make sure your cursor is flashing

next to PMT. It doesn’t matter what value is in the PMT. Your calculator will put in the correct

payment when you tell it to compute the payment. Hit the green ALPHA button the ENTER.

Answer:

D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges

Step-by-step explanation:

Price per pounds of bananas = b

Price per pound of oranges = b + $0.75

Diego buys:

3 pounds of bananas = 3(b) = 3b

2 pounds of oranges = 2(b + 0.75)

Amount paid by Diego is expressed as:

3b + 2(b + 0.75) = 4.50

To find the price per pound of each fruit, use the equation above to find the value of b:

3b + 2b + 1.50 = 4.50

Combine like terms

5b + 1.50 = 4.50

5b + 1.50 - 1.50 = 4.50 - 1.50

5b = 3

5b/5 = 3/5

b = 0.6

Price per pound of banana = b = $0.6

Price per pound of oranges = b + $0.75

Plug in the value of b

= $0.6 + $0.75

= $1.35

Answer:

10times

Step-by-step explanation:

there is a 50/50 chance of both 20 divided by 2 is 10

After tossing 20 times a coin probability of getting heads is equals to 10.

" Probability of any event is defined as the ratio of total number of favourable outcomes to the total number of outcomes."

Formula used

[tex]Probability =\frac{Number of favourable outcomes}{Total number of oucomes}[/tex]

According to the question,

Number of times coin tossed = 20

When we toss a coin there only two outcomes Head and Tail.

As per the formula,

Probability of head = 1 / 2

Probability of tail = 1 / 2

Therefore,

Probability of getting head when Karla tossed coin 20 times is equals to 20 / 2 = 10 times.

Hence, after tossing a coin 20 times  probability of getting heads is equals to 10 times.

Answer:

1) y=1/5x +0.8

2) y= -2x +10

Step-by-step explanation:

It's been a while, but I think this is right:

1)

For 2 lines to be parallel they must have the same slope

Recall that the equation of a line is

y-y1 = m (x- x1)

m being slope

So looking at equation 1, we can tell that the slope is 1/5 because it has already been distributed to the x.

So we know our equation will look something like this

y-y1 = 1/5 (x- x1)

We also know that the line passes through the point (8,1)

So, you plug in those points to your equation

y- 1 = 1/5(x - 8)

Simplifying and distributing the equation, we end up with

y= 1/5x + 0.8

(if you would like me to explain the simplification plz ask in a comment.)

2)

First you have to move -x from the left side of the equation to the right, making the equation

2y= x+10

then divide by 2 on both sides (im writing x/2 as 1/2x, because they are the same)

y= 1/2x + 5

For 2 lines to be perpendicular they must have the opposite reciprocal slope

Meaning if you had a slope of 2, the opposite would be -2 and the reciprocal would be 1/2, so your slope would be -1/2

Knowing this and keeping in mind our equation of a line from the first question, our slope of a perpendicular line (or m in our equation) of y= 1/2x + 5

would be -2

So far we have an equation that looks like

y-y1 = -2 (x- x1)

So now we plug in our points (6, -2)

(y- -2)

y + 2 = -2 (x - 6)

Simplifying and distributing the equation, we end up with

y= -2x +10

(if you would like me to explain the simplification or have a question don't hesitate to ask in a comment.)

Answer:  1.)  y = 1/5 x - 3/5

2.) y = -2x + 10

Step-by-step explanation:

1.)  Keep the same slope. Substitute the y and x-values from the given coordinate into the slope-intercept form and solve for the new b

1 = 1/5(8) + b    1 = 8/5 +b .subtract  8/5 form both sides:

-3/5 = b

y = 1/5 x - 3/5

2.) Rewrite the given equation in slope-intercept form

-x + 2y = 10  becomes y= 1/2 x +10

Take the reciprocal of the slope and reverse the sign:  1/2 becomes -2

Substitute the y and x-values from the given coordinate into the slope-intercept equation and solve for b.

-2 = -2(6) + b

-2 = -12 + b   Add +12 to both sides

10 = b

y = -2x + 10   Standard form: 2x + y = 10

Answer:

how does M what

Step-by-step explanation:

Answer:

Currently temperature = 35°F

Rate of descend = 4°F

We have to reach = -1°F

Temperature to get cooled down = |-1 + 35| (The two lines mean absolute value)

=> 36°F

Hours = Total temperature to get cooled / Rate

=> 36 / 4

=> 9 hours

Equation = 4x = |1 + 35|
